    Abstract:
    We determined whether the serum lipoprotein levels in insulin-dependent diabetic patients (IDDM) with nephropathy and in patients on haemodialysis or continuous ambulatory peritoneal dialysis were affected by beta-blocker therapy. A case control study was performed in 18 IDDM patients with diabetic nephropathy, in 18 patients receiving chronic haemodialysis (HD) and 16 patients undergoing continuous ambulatory peritoneal dialysis (CAPD). In IDDM patients with diabetic nephropathy very low density lipoprotein-cholesterol (VLDL-CHOL) (0.680 +/- 0.17 vs 0.197 +/- 0.04 mmol/l, p = 0.004), total triglycerides (1.71 +/- 0.23 vs 0.808 +/- 0.14 mmol/l, p = 0.004) and very low density lipoprotein triglyceride (VLD-TG) were higher in the beta-blocker therapy group. In haemodialysis patients, beta-blocker therapy caused no significant changes in the serum lipoprotein profiles compared to the control group. In patients receiving continuous ambulatory peritoneal dialysis VLDL-CHOL was significantly higher (1.47 +/- 0.24 vs 1.08 +/- 0.21 mmol/l, p = 0.042) and cholesterol-high density lipoprotein (HDL-CHOL) was lower in the beta-blocker therapy group. The elevated VLDL-CHOL level (0.96 +/- 0.12 vs 1.24 +/- 0.14 mmol/l, p = 0.021) was correlated with the duration of CAPD in patients receiving beta-blocker therapy. Antihypertensive therapy with beta-blockers in IDDM patients with persistent proteinuria and in patients on continuous ambulatory peritoneal dialysis appears to adversely effect serum lipoproteins which may add to their cardiovascular risk.
